Ali Builds model planes. He uses a scale of 8 cm to represent 1.8 m.
Question #1. What is the ration a length on the model to the actual length on the plane? Length:
1.8m ≈ 8 cm
72m × x cm
72/1.8m ≈ 40 m.
40 × 8cm ≈ 320cm
Question #2. A model has a length of 60 cm. What is the actual length of the plane?
I'll get back to you as soon as possible
